Centers for Disease Control (CDC) waterborne disease surveillance provides information that can help prevent future disease and outbreaks while providing important information on how germs, chemicals, or toxins spread, and which types of water are linked to people getting sick.
Water contaminated with germs, chemicals, or toxins can lead to waterborne illness if you drink it, breathe it in, or it touches your skin, eyes, ears, or other mucous membranes. By collecting data on the types of water, water systems, settings, and agents (what spreads the disease) that are linked to waterborne illness, we improve our understanding of waterborne illnesses and can better guide prevention efforts.

Below is a cross-reference of those symptoms and medical conditions, under medical specialization categories.
